M51909P Datasheet | Mitsubishi Electric

MITSUBISHI LINEAR ICs M51907P M51909P a-STEP BAR TYPE LED LEVEL INDICATOR DESCRIPTION The M51907P/M51909P is a semiconductor integrated circuit consisting of a Circuit designed for LEO level meters. It is capable of bar type display for 8 LEOs according to a input level. AC or DC signal can be inputted because of built-in superior half-wave rectification OP Amp. Output is a cascade connection of a pair of LEOs, so current for display is half. Display level of the M51907P is logarithmical scale,+ 5, +2,0,-2,-5,-8,-13,-18 dB. The M51909P is a panion products to the M51907P, display level is linear scale, 156mV step. Features - Built-in superior half-wave rectification OP Amp. Cut off...
